In a production environment, the overcloud, which has it's metadata server as default route until we kill file injection, may not be the default route, so we need to be able to influence routing. Change-Id: I698682183a301141e224e5713a49b23f8e6c863e

Install and configure OpenStack Networking Openvswitch agent.
Configuration
The physical interface and bridges to use to bridge traffic onto can be configured via Heat Metadata. For example:
neutron:
ovs:
public_interface: vlan25
public_interface_raw_device: eth2
public_interface_route: 12.34.56.78
physical_bridge: br-ctlplane
physical_network: ctlplane
network_vlan_ranges: ctlplane
bridge_mappings: ctlplane:br-ctlplane
If public_interface and physical_bridge are not set, no bridges will be connected directly. This is normal for neutron hosting virtual machines when using an overlay network (e.g. GRE tunnelling). Some of the other fields will be ignored in this case. Most of them map 1:1 with their counterparts in the OVS section of ovs_neutron_plugin.ini If public_interface_raw_device is set, public_interface must be a vlan device, and the vlan device will be created using the raw device during os-collect-config configuration.
Once the public interface is configured, public_interface_route (if set) will replace the default route's next hop. The hop this replaces will be added as the next hop for 169.254.169.254/32. This permits routing default traffic out through a hardware router without breaking the ability to contact a bare metal metadata server.
